react-redux

问题 I just started exploring react-redux hooks and I was curious how to return a promise if I am using thunk and useDispatch() . Essentially I want to achieve the following: const dispatch = useDispatch(); dispatch(myAction(...args)).then((result) => { ...do something with result }); When my action looks like this: const myAction = (arg1, arg2) => { return (dispatch, getState) => { Promise.resolve(arg1 + arg2); } } I've simplified my problem a lot, but that is essentially what I'm dealing with.

问题 This is a newbie question for react-redux I spent a couple hours hunting around before finding so I am posting the question and then answering for posterity and also maybe code review. I am using react-redux to create a game where I want to use the WASD keys to move a character around a small map. (This is just a practice example for a larger endeavor). The map simply consists of a bunch of colored <div> s. As I understand it I need to somehow bind the keypress event to something in the React
